If a master key or the aluminum key-code tag is not available, a Lexus dealer or certain locksmiths can obtain the key code from a restricted-access database. These businesses can also access a service utility to reprogram the immobilizer if all registered master keys have been lost. If a Lexus dealer is not available, please refer to www.aloa.org to find a bonded/registered locksmith who performs high-security key service. Keeping the Key Safe Replacing an immobilizer key may be costly. We advise you to keep a spare master key and the aluminum keycode tag in a safe place. If you record the key code in more than one place, do not record it in a way that can be easily identified and associated with the vehicle. For example, don't leave the code somewhere that can be accessed by a valet. It is wise to keep a copy of the key code outside of the vehicle. If the vehicle was delivered with less than two keys, consider having a Lexus dealer or a qualified locksmith make a duplicate key before you need it. Other Benefits and Assistance 9
